Question

Choose the correct options:

(a) the cell reaction will be spontaenous if c1 > c2 .
(b) if c2 > c1 , current will flow from cathode to anode.
(c) if c1 > c2 , current will flow from cathode to anode.

Answer 1

The concentration difference between the cathode and anode determines the flow of current in a cell reaction.

Step-by-step explanation:

The cell reaction will be spontaneous if c1 > c2. When the zinc(II) ion concentration is greater in the cathode, it indicates a greater driving force for zinc reduction, leading to a spontaneous reaction.

If c2 > c1, current will flow from cathode to anode. This is because the cathode, where the reduction occurs, has a higher concentration of ions and becomes the positive terminal.

However, if c1 > c2, current will flow from anode to cathode. This is because the anode, where the oxidation occurs, has a higher concentration of ions and becomes the positive terminal.
